Hello, Same problem happened on my windows. When I run "openCONFIGURATOR.bat" under openCONFIGURATOR-1.4.1\windows\tools, it said cannot found "tclsh86" in my system. I found a file named "tclsh86t" under ActiveTcl folder, so I copied the file and rename it as "tclsh86", openConfigurator.exe can be launched. Hope this can help.
